Marinite® Calcium Silicate Boards Are Formable, and Formidable!

Calcium silicate is a white, free-flowing powder derived from limestone and diatomaceous earth combined together. Calsil is commonly used as a safe alternativeto asbestos products for high temperature insulation materials, and is also used for passive fire protection. When compressed into boards, Marinite takes on a life of its own and has very handy application capacities in numerous industries.

Very popular as a structural insulation material, Marinite is used in stoves, commercial baking ovens across the country, as back-up insulation in high-temperature furnaces, and for personal protection in high-heat settings as well as for high-temperature electrical insulation. Marinite can be found in all heat-treating industries as well as within the petrochemical industry, aluminum industry,glass and ceramic industry, and even within the world of appliance manufacturing.
